Hi All,<br><br>I am new to eeglab/matlab. I want to know statistics for groups of channels in the ERSP domain in a study. For example, I want to know differences between independent variables A and B when considering evoked power at frontal electrodes (F3, F4, F5, Fz). I can select multiple channels and see significant differences in the power spectrum but not ERSP. The help says that there is a merge channels option but I'm not sure that is what I want and can not find the button to try it out. Any advice is much appreciated.<br>
